Stings maphack.

Hello, I'm using stings maphack and I keep running into halt error line 250. It happens when I exit a game and start again at either act 1 or act 3 spawn. (In act 1 it crashes when I try to use waypoint, in Act 3 it crashes on the bridge)
Is there a way to fix this annoying error or do I have to
1) Keep exiting at act5
2) Close/Reopen the client every time I exit a game and want to join a lower difficulty game.
